Changelog

4.0.0

Improve performance by changing the method for detecting whether a DOM node is focusable or not. It's expected that this change will not affect results; but this is a major version bump as a warning for you to check your edge cases before upgrading.

3.1.2

Fix reference to root element that caused errors within Shadow DOM.

3.1.1

Allow module to be imported by non-browser JavaScript.

3.1.0

Add tabbable.isFocusable and tabbable.isTabbable functions.

3.0.0

Add [contenteditable] elements.

2.0.0

Add <audio> and <video> elements with controls attributes.
Only consider radio buttons tabbable if they are the checked on in their group, or if none in their group are checked.

Fix bug causing SVG elements to precede elements they should follow in the tab order in IE.

1.1.2

Ensure querySelectorAll receives a string argument.

1.1.1

Fix crash when you call tabbable(document) (passing the document element).

1.1.0

Add includeContainer option.

1.0.8

Allows operation against elements that reside within iframes, by inspecting the element to determine its correct parent document (rather than relying on the global document object).

1.0.7

Ensure stable sort of tabindexed elements even in browsers that have an unstable Array.prototype.sort.

1.0.6

Check tabindex attribute (via getAttribute), in addition to node.tabIndex, to fix handling of SVGs with tabindex="-1" in IE.

Children of visibility: hidden elements that themselves have visibility: visible are considered tabbable.

1.0.4

Fix IE9 compatibility.

1.0.3

Further improvements to caching.

Fix overaggressive caching that would prevent tabbable from knowing an element's children had changed.

Initial release.
